There is no denying the fact that Delhi is counted amongst the top polluted cities across the world. While as per the World Health Organization (WHO), Delhi charts on 11th in this list, it also tops the list of ten top most polluted cities in India.
The level of pollution in the national capital has been a major concern for WHO and NGT (National Green Tribunal) as it causes major health hazards in populates of the city. The main reason for the rising pollution levels in the capital of the country can be attributed to the smoke emitted by factories and vehicles, burning of fossil fuels and last but not the least, by the crop residue being burnt in the adjoining states.
In general, the months from March to May are attributed with wheat burning which is the time for the blowing of the northwesterly winds.
As Punjab and Haryana lie towards northwest or Delhi, these winds carry smoke and pollutant particles towards Delhi. Moreover, as the city is densely populated with not much vegetation, these pollutants get mixed with the already polluted city that aggravates the situation.
Though NGT has completely banned stubble burning, yet a massive increase in the number of crop fires in Delhi and adjoining states especially in Punjab and Haryana has been reported. NASA has recently revealed some pictures of enormous crop residue burning in Haryana and Punjab.
NASA’s Fire Mapper has exposed a few images that show a massive upsurge in the number of fires that out broke between April 25 and May 3. You can check the crop burning images revealed by NASA here:
